The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
2-((1H-Indol-5-yl)amino)-6-((2,4-difluorophenyl)sulfonyl)-8-methylpyrido[2,3-d]pyrimidin-7(8H)-one (CAS 1312471-39-8) is a high-purity analytical reference standard with the molecular formula C22H15F2N5O3S and a molecular weight of 467.45 g/mol.
2-((1H-Indol-5-yl)amino)-6-((2,4-difluorophenyl)sulfonyl)-8-methylpyrido[2,3-d]pyrimidin-7(8H)-one (C22H15F2N5O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
